Visualización de imágenes de la tarjeta sd en gridview android

Im Mostrar imágenes de una carpeta específica en la tarjeta sd en GridView hasta saber que todo funciona bien todas las imágenes se muestran en la vista de cuadrícula, pero cuando cambio la orientación de la pantalla se bloquea. A continuación está mi código y Crash Log:

import java.io.File; import android.content.Context; import android.net.Uri; import android.os.Environment; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.GridView; import android.widget.ImageView; public class ImageAdapter extends BaseAdapter { private Context mContext; File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MYPICS" + File.separator); private File[] fileName = root.listFiles(); int count=fileName.length; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return fileName.length; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { Uri uri = Uri.fromFile(fileName[position]); ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(8, 8, 8, 8); } else { imageView = (ImageView) convertView; } imageView.setImageURI(uri); return imageView; } } 

Estoy recibiendo la memoria de error, Abajo está mi Logcat:
